Ethereum creator Vitalik Buterin has introduced a new philosophy called d/acc, which promotes a balanced approach to technological development. The philosophy emphasizes defense, decentralization, and human flourishing. Buterin's philosophy is a counterbalance to the unrestricted techno-optimism of figures like Marc Andreessen. Buterin acknowledges that progress is not always linear and calls for more collaboration in technological development. While both Buterin and Andreessen recognize the benefits of technology, their philosophies are incomplete and open to debate.
